SPECIFICATION forming part of Letters Patent No. 292,920, dated February 5, 1884.

Application filed November 26, 1883.

To all whom it may concern Be it known that I, Gonnnmos KDIPLEN, residing at Chicago, in the county of Cook and State of Illinois, and a citizen of the United 5 States,have invented'certain new and useful Improvements in Presses, of which the following is a full description, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation; Fig. 2, a vert-i-.

" cal, section; Fig. 3, a top or plan view; Fig.

4, a cross-section on line 1 l of Fig. 2; Fig. 5, an inside elevation of the casing inclosing the parts used in raising or lowering the shelves or division-plates; Fig. 6, asimilar view withthe I 5 inner casing-plate removed; Figs. 7, 8, and 9, details of the movable shelf-supports; Fig. 10, adetail view, showing a portion of the devices used for operating the chains and stops.

My improvements relate to that class of hydraulic presses which are used for pressingout oil from flaxseed and cotton-seed, and for other similar purposes; and its object is to provide means for easily and readily operating the di vision plates or boxes, and to so manage them 25. that a greater number can be used in the same space without a corresponding loss of space capacity in the press, and so that the press can be made to perform its service with less labor with increased capacity and with increased results. Its nature consists in the several improvements and combinations of parts l1ereinafter described and claimed as new.

clined grooves in the sliding supports 1?; p, projecting points orarms on slides I; (1, pin or projection for supporting the back ends of the slides B; r, ledges or grooves for keeping the inner or forward ends of the slides P in position; s,'limit-stop for the segment S; t, upward limit-stop for the chains; to, weight. The hydraulic press and its plunger B are made in the usual form, or in any suitable form, and are provided with the usual pipes I and exhausts for the proper operation of the pump. I

The bed-plate C, the cap-plate D, and their connecting rods or posts E are also made in the usual manner, as shown. 6 5

The plates G are made in the usual manner and provided with ordinary mats in preference to boxes.

Taking a press of this or its equivalent construction, I apply to its sides the casingsF F, which are usually made of cast-iron in the form shown.

' The plates II may be made of cast or wrought iron, and the casings are firmly attached to the bed and cap plates of the press. casings or columns F F are provided with holes at their backs, to receive the pins q of the slides I, and also. side ledges to support the front or inner end of the slides. It will be evident, however, that grooves maybe used in the place of the ledges. (Shown at Fig. 6.) These casings or columns have placed within them shafts I I and the ends of an upper crossshaft, J, which shafts are provided within the casings with sprocket-wheels N, which are 8 driven by and carry the chains 0. These chains are provided with traveling heads or blocks an, firmly connected therewith, which blocks are provided with pins 91, arranged to properly engage with the slots or grooves 0 of go the slides 1?. These heads or slidesare held in. position by s1 itable grooves in the casing and in the guidegplate Q, as shown in Fig. 4. As shown in Fig. 2, only the casing I is provided with an upward limit-stop, i; but such 5 stop may be placed in either or both of the casings. vVithin the casing F, I place, in addition to the parts just described, the shaft K, upon which is placed the gear-wheel L, the ratchet- The 75 wheel a, the broken-gear wheel 0, and the spring g. The wheel L and ratchet a are firmly attached to the shaft, while the broken gear e is free and has a partial rotation upon the shaft. One end of the spring 9 is attached to the shaft and its opposite end to the casing. The object of this spring is to return the shaft.

' This, however, may be omitted, and a weight,

10, applied to take the place of it, as shown in Fig. 7. This shaft is rotated by the lever T and segment S, the'segment engaging with the teeth of the wheel 6, which wheel is provided with a spring-pawl, it, so that whenever the lever T is depressed the wheel 6, having its pawl engaging with the ratchet a, rotates the shaft to the extent of one notch, which rotation rotates the wheel L, that engages with the wheel M on the shaft 1, and a rotation of this wheel causes a rotation of thesprocket-wheel on the same shaft, causing a movement of the chain to the extent of the distance of the space between two of the arms P and the thickness of one, the pin it starting midway between two of the slides and stopping midway between the one across which it passes and the next one. The same movement causes the shaft J to rotate, and through the said shaft gives a corresponding movement to the block m and chain in the casing F. This operation is continued by raising and depressing the lever T, e L011 complete movement causing the ratchetwheel a to advance one step. The tendency of the parts to return when relieved from the operation of the lever T is prevented by the pawl or dog I), whichdog is pivoted to the eas- 1ng at c and to the sliding bar R at (I. At each movement of the shaft K and wheel Lits return movement is prevented by the dog b dropping into the ratchet a on the opposite side, thus preventing the weight of the parts lifted from causing a return movement of the wheel L.

The slide R is provided with a notch, t, which is so located and arranged in reference to the latch j that when the movements just described are taking place the latch does not drop into the notch, but when the plates are lifted by the press, so that the upper one strikes the arm or lever Z, the sliding bar R is raised, so

that the latch 9' will drop into the notch and hold the bar in its elevated position, which po sition keeps the pawl I) out of contact with the ratchet-wheel a, and holds it in this posit-ion until the'press descends and the lower part strikes the projecting arm of the latch j and throws it out of the notch i, when thebar R drops and the pawl I) again goes into operation as before. The arm of the latch j and the arm or lever Z project through the casing H, as shown in Fig. 5, so as to be operated by the plates as just described.

The lever T is prevented from moving or being moved too far in an upward direction by the limit-stop s. The framing or .fioor of the building in which the press is placed forms the limit of the downward movement, the lever T usually being placed so near the floor that it can be operated by the foot as well as by hand.

The slides P are eachprovided at their rear end with pins or projections q, which enter cor,- responding holes in the casing. 'Near their rear ends they are enlarged, so as not to require very steep inclines, and are provided with inclined grooves 0, which operate to advance or retract the shells according to the direction of the movements of the heads or blocks m and their pins a. They are also provided with projections or arms 1), which, when the slides are retracted, do not operate beyond the plates H, but when moved in the opposite direction protrude, as indicated by the dotted lines, for the upper ones in Fig. 2, in which position they extend under and hold up the plates G.

The operation is as follows: WVhen the heads m are in the upper position, (shown in Fig. 2,) the slides p are all retracted, and they are in this position when the press is filled and ready for the application of power to the plunger B, as when in this retracted position the plates are all free to be moved upward. \Vhen the pressing is completed and the press ready to be let down, the top plate will be above and the second plate in line with the upper set of slides, I The spring 9 or the weight w, whichever is used, gives the chains a constant tendency to return the blocks m to their lowest position. \Vhen, however, the pin it strikes against the incline of the groove 0, the slide will not operate by reason of its being in contact with the second plate from the top. Consequently the pin M will be held in position until the second plate (as the water goes out from the press) passes below the slide, and, when below, the pin a, acting upon these upper slides, will project them inward, as indicated by the dotted lines, and thus hold the upper plate upon them. The slides being all arranged and spaced to come in similar contact with the plate below the one which is to be held by them, they stop the descent of the pin n until the slides can move as before and hold their proper plate. Then the plates and plunger have all thus descended, the-last one will come in contact with the projecting arm of the latch j and force it out of the notch i, when the bar R will drop with the dog I), so that the operation of the ratchet a can be re sumed for giving the pins n a reverse movement. When the press is down or in this position, the cakes are removed, and the press is ready for reversing. To perform this operation, the material to be pressed is properly placed in the first space. A down movement is then given to the lever T, which is so arranged and timed with the gear that it will cause the pin 12 to pass through the next plateabove the bed-plate and drop it onto the ma- 7 terial just placed in the lower space. The material in this space is then placed in position and another downward movement given to the lever T, when the next plate above is dropped by the retracting of the slides P onto the ma terial in the second space, and so on until all of the spaces are filled. By'this arrangement for dropping the plates onto the material I obtain three important advantages or results, it

being understood that in pressing oil from seeds of all kinds they are usually placed in the press hot. By dropping the plate onto the material a circulation of the air is prevented, and the heat is more perfectly retained. By dropping the plates onto the material there is a gain of space for the succeeding fillings to the extent of the distance which the plate is dropped, which space increases as the number of spaces filled increases, so as to save considerable lifting at the upper end of the press, besides giving the workmen a wider space to operate in. By this arrangement I am also enabled to use more plates than can be used without it, twenty plates being used in presses where only sixteen could be used without my improvement, and without requiring any perceptible addition of time in filling the press, owing to the better facilities afforded the workmen. When the plate at has reached the top, it has retracted all of the slides, so that the plates are free to move upward when the power is applied. After the power is applied the plates are let down, as before described, and the operation repeated.

These presses are usually arranged in sets of four. so that by the time the last one is filled the first one is ready to be discharged of its cakes, and thus there is no time lost or wasted. As each set of slides is separate andindependent there is no chance for accidents or breakage in this construction, as it is impossible for the slides to project until the press is ready for them to be projected inwardly; butin case of any accident the slides can all be left retracted, and by taking four of the plates out of a twenty-plate press the press can then be used in the manner heretofore practiced, so that it would not be thrown out of use entirely; but as the press is arranged it is almost impossible for any accident to happen by reason of the parts which I have added thereto.

Having thus described my improvements,

what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of the casings or hollow columns F F, having the movable slides within them, with the base and cap plates 0 D of a press, substantially as and for the purpose described.

2. The combination of two or more slides, I with the casingsF Fand plates G, substantially as described.

3. The combination of the sprocket-wheels N, mounted upon suitable shafts, with the chains 0, movable heads or blocks m, having pins a, and the slides I, having inclined grooves o, substantially as set forth.

4. The combination of the shaft K, the gearwheels L M, shaft I, sprocket-wheels. N, and shafts J and I, substantially as specified.

5. The combination of the ratchet-wheel a with the broken-gear wheel 6, spring-dog 71, segment-lever TS, and a spring or weight, sub stantially as described.

6. The combination of the segment-lever T S, the broken-gear wheel 0, ratchet-wheel a,

dog 7i, and wheels L M for rotating the shaft I, substantially as set forth. i

7. The combination of the ratchet-wheel a with the pawl or dog I), sliding bar R, having the notch i with the latchj, and lever or pro jection Z, substantially as specified.
